Oceanic uptake of anthropogenic carbon dioxide (CO2) from the atmosphere has changed ocean biogeochemistry and threatened the health of organisms through a process known as ocean acidification (OA). Such large-scale changes affect ecosystem functions and can have impacts on societal uses, fisheries resources, and economies. In many large estuaries, anthropogenic CO2-induced acidification is enhanced by strong stratification, long water residence times, eutrophication, and a weak acid-base buffer capacity. In this article, we review how a variety of processes influence aquatic acid-base properties in estuarine waters, including coastal upwelling, river-ocean mixing, air-water gas exchange, biological production and subsequent aerobic and anaerobic respiration, calcium carbonate (CaCO3) dissolution, and benthic inputs. We emphasize the spatial and temporal dynamics of partial pressure of CO2 (pCO2), pH, and calcium carbonate mineral saturation states. Examples from three large estuaries-Chesapeake Bay, the Salish Sea, and Prince William Sound-are used to illustrate how natural and anthropogenic processes and climate change may manifest differently across estuaries, as well as the biological implications of OA on coastal calcifiers.The Deepwater Horizon oil spill was the largest, longest-lasting, and deepest oil accident to date in US waters. As oil and natural gas jetted from release points at 1,500-m depth in the northern Gulf of Mexico, entrainment of the surrounding ocean water into a buoyant plume, rich in soluble hydrocarbons and dispersed microdroplets of oil, created a deep (1,000-m) intrusion layer. Larger droplets of liquid oil rose to the surface, forming a slick of mostly insoluble, hydrocarbon-type compounds. A variety of physical, chemical, and biological mechanisms helped to transform, remove, and redisperse the oil and gas that was released. Biodegradation removed up to 60% of the oil in the intrusion layer but was less efficient in the surface slick, due to nutrient limitation. Photochemical processes altered up to 50% (by mass) of the floating oil. The surface oil expression changed daily due to wind and currents, whereas the intrusion layer flowed southwestward. A portion of the weathered surface oil stranded along shorelines. Oil from both surface and intrusion layers were deposited onto the seafloor via sinking marine oil snow. Akti-1/2 mouse of stranded or sedimented oil were low, with resuspension and redistribution transiently increasing biodegradation. The subsequent research efforts increased our understanding of the fate of spilled oil immensely, with novel insights focusing on the importance of photooxidation, the microbial communities driving biodegradation, and the formation of marine oil snow that transports oil to the seafloor.America is at a critical crossroads in history as the COVID-19 pandemic expands. We argue that the failure to respond effectively to the pandemic stems from the nation's protracted divergence from the democratic ideals, we purport to value. Structural racism and class-based political and economic inequity are sustained through the failings of the nation's democratic institutions and processes. The situation has, in turn, fostered further inequity and undermined science, facts, and evidence in the name of economic and political interests, which in turn has encouraged the spread of the pandemic, exacerbated health disparities, and escalated citizen tensions. We present a broad vision of reforms needed to achieve democratic ideals which we believe is the most important first step to achieving true political representation, achieving a resilient and sustainable economy, and fostering the health of vulnerable communities, workers, and the planet.Turner syndrome is a rare condition affecting 1 in 2500 female births and yet is the most common sex chromosome abnormality in women. Described as a cradle-to-grave condition, it requires life-long multidisciplinary management. #link# Accelerated atresia of the primordial follicular pool leads to premature ovarian insufficiency, which is an almost inevitable feature of Turner syndrome, especially in 45XO karyotype. Many patients will have had their diagnosis made in childhood and require paediatric endocrinology management especially for induction of puberty. At the age of 18, patients may then be transitioned to an adult service. Continuation of multidisciplinary care for these women requires input from specialist services in menopause care, reproductive medicine and high-risk pregnancy, cardiology, endocrinology, bone health and psychosocial care. A gynaecologist may take on the mantle of lead clinician especially during the perceived reproductive years of a Turner syndrome patient's life, hinging together management input from other disciplines. This review attempts to summarise an overview of the involvement of such a multidisciplinary team in the management of a single but complex condition, through the lens of a gynaecologist.Purpose The Lidcombe Program is an efficacious and effective intervention for early stuttering. The treatment is based on parent verbal response contingent stimulation procedures, which are assumed to be responsible for treatment effect. The present trial tested this assumption. Method The design was a parallel, open plan, noninferiority randomized controlled trial. In the experimental arm, the five Lidcombe Program verbal contingencies were removed from parent instruction. The primary outcome was beyond-clinic percentage syllables stuttered at 18-month follow-up. Seventy-four children and their parents were randomized to one of the two treatment arms. Results Findings of noninferiority were inconclusive for the primary outcome of stuttering severity, based on a margin of 1.0 percentage syllables stuttered. Conclusions The inconclusive finding of noninferiority means it is possible that verbal contingencies make some contribution to the Lidcombe Program treatment effect. However, considering all primary and secondary outcomes, an overriding impression from the trial is a similarity of outcomes between the control and experimental arms. The clinical applications of the trial are discussed, along with further research that is needed.
